Huygens wave theory:
Huygen's wave theory is not correct in all respects.
2. It assumes simply that light energy is propagated as a wave.3. At the time of his proposition Huygen's did not have any idea about wavelength or about the transverse nature of light.4. So Huygens wave theory was Later modified by Thomas Young and Fresnel.5. They introduced the concept of wavelength and assumed that light waves are transverse.6. By these assumptions they could successfully explain not only the rectilinear propagation of light but also the phenomena of interference, diffraction and polarization of light.
The experimental set-up for producing Newton's ring is shown in fig. (A). A plane-convex lenses L of large radius of curvature with its convexities is placed on a plane glass plate
Charles' law (J.A.C. Charles; c. 1787) At constant pressure the volume of ideal gas is proportional to the thermodynamic temperature of that gas.

Conductor: Conductors are those substances which permit electric current to passes easily by them. e.g. Metal, impure, water etc.
how to solve kcl
It makes sense that copper should be used because it could heat up faster, making the event more efficient.
